VALLEY FOR ROOFS.

SPECIFICATION forming part of Letters Patent No. 607,425, dated July 19,1898.

' Application filed November 17,1397. Serial No. 658,785. on) model.)

To all whom it may concern.-

Be it known that I, GERHARD F. DRoUvE, a citizen of the United States,and a resident of Bridgeport, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements inValleys for Roofs,of which the following is a specification.

My invention relates to an improvement in roofing-valleys; and itconsists in certain details of construction to be more fully set forthin the following specification.

To enable others to understand my invention, reference is bad to theaccompanying drawings, in which- Figure 1 represents a perspective viewof my improved valley. Fig. 2 is a diagram of the end of .two houses,showing the mannor of attaching the valley. Fig. 3 is an end view of theValley, showing the position the central elevated portion or housingwill assume under expansion. Fig. 4 is a view similar to Fig. 3, showingthe effect of contraction.

Its construction and operation are as follows:

The improvement consists in making the valley of a single piece ofmetal, as shown at Fig. 1. The wings 1 and 2 are bent at the properangle to conform to the angular construction or pitch of the two roofs 3and 4. (Shown at Fig. 2.)

The central portion of the valley is elevated an inch or more above thewings, and such raised portion consists of the sides 5 and 6 and theclosed crown 7 In the drawings this crown is shown circular; but this isimmaterial, as it can assume any form desired. The sides 5 and 6 may beformed at any angle with each other instead of being nearly parallel, asshown, the gist of the invention consisting in forming an upwardelevation of the stock in a single piece of metal to form a housing openat the bottom and closed at the top, so as to form the open mouth 8, andthis open mouth is placed directly over the meeting angle of the roofs,as shown at Fig. 2. The apexes of the angles 9 and 10, formed by thewings and sides of the said housing, serve as gutters to carry off thewater from each of the roofs. This housing also prevents the Water fromone roof flowing up the opposite roof and under the metal coveringthereof, such water being caught by said housingand conveyed from bothof said roofs. This U-shaped central portion will enable the sheet-metalroofing to contract or expand without affecting or disturbing theconnection between the two roofs. In Fig. 3, as before mentioned, isshown how it operates under expansion, and in Fig. 4 how it will beaffected by contraction. In either case it will be observed that theintersection of the roofs is fully protected at all times.

The hook portions or laps 11 of the wings are adapted to unite with hookportions 01' laps of the rest of'the sheet-metal roofing. (Not shown.)

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The herein-described improvement in valleys for roofs which consistsin forming an indentation in the body of a metal sheet and in the undersurface thereof, so as to force the metal in the form of a housing abovethe upper surface to protect the intersection of 'two roofs, theremaining portionof the sheet forming wings adapted to rest on saidroofs,

the intersection of the said wings and sides of the housing forminggutters or channels for conveying off the water, the sides of saidhousing adapted to approach or recede from each other to compensate forcontraction or expansion, for the purpose set forth.

2. The herein-described improved valley constructed of a single piece ofmetal, an indentation made in the under surface thereof, so as to forcethe metal in the form of a housing above the upper surface so that theopen mouth of such housing will span the intersection of two roofs, theremaining portion of the metal sheet forming wings on each side of saidhousing adapted to rest on said roofs, the intersection of the saidwings and vertical sides of said housing forming gutters or channels forconveying off the water, the vertical sides of said housing adapted toapproach or recede from each other to compensate for contraction orexpansion, for the purpose set forth.

Signed at Bridgeport, in the county of Fairfield and State ofConnecticut, this 23d day of October, A. D. 1897.
